I just want to say, I love showdown this year. I never really enjoyed playing offline last year, but showdown changed that for me. It relaxes me 95% of the time.
I just think it should get the March To October treatment. Even if I fail the final boss, I want to feel like I've made at least a little progress. Maybe something along the lines of 1 voucher per mini-boss and then 3 at the end? Or at the very least, one voucher after the second mini-boss.
I think this would alleviate a lot of the frustrations most of us have with showdown. It's easy to get a bit miffed when you lose the final one and have just spent 30 minutes to an hour for no progress. At least even if I lose the finale, I know I made a little bit of progress.
